Home Depot has 32oz bottles of Windex advertised for 3 for $2.98. Go to this http://www.rightathome.com/tipsandcoupons/ site and print $1.00 off Windex coupons (there are also other coupons for you to print ). This site allows you to print 2 of each coupon you select. Go to Home Depot and purchase 3 bottles of Windex with your coupons. That makes them 3 bottles for under $1.00! Cheaper than the dollar store! Just in time for Spring cleaning!
